Both right side doors did this on our 2005 FEH. We used the 3M spray. I took the entire door panel off and set it on the table. I used a dry toothbrush and vacuum to clean away all the crud, which appeared to be a combination of glue and foam, from both the door and the leather. I had to stop often, wash the toothbrush, and dry it completely before continuing to clean. Follow the 3M instructions for coating and a waiting time. I used painters tape and paper to cover the other areas of the door panel to prevent overspray of the 3M. It is a 2 person job! May I suggest also starting at the hole for the door handle and getting that inside edge in place completely first. This may be a three person job! Then work your way from the door handle back. Go slowly, and you can use a plastic putty knife to get the leather down into the crease along the edge. On our first door, we started at the wrong end - away from the handle opening, and ended up with a homemade seam on the strip in front of the handle because it is easy for the leather to stretch. On the second door, we still had some stretch, but because we worked from front to the rear of the panel we could just trim a little with a razor blade. Both panels look good, with the exception of the seam on the front. It looks ok, it is just noticible. The 3M is holding well. The left side panels have not shown any signs of peeling. Hope this helps someone else!
